Definitions

  • the present invention relates to devices and systems for dispensing multiple volatile materials, including but not limited to scents into the environment.
  • Devices are currently available for dispensing volatile materials, such as a single scent into a room and in automobiles. Examples of devices for dispensing a single scent into a room include GLADE PLUG INS® plug in room fresheners manufactured by S. C. Johnson. Devices capable of dispensing scented materials are also described in the patent literature. Examples of such devices are described in: U.S. Pat. Nos. 4,549,250; 4,714,984, 4,695,434; 4,629,604; and 5,805,768; and in PCT Publication WO 97/02076 and Canadian Patent Application 2,222,838; PCT Publication WO 00/121143; and U.S. Patent Publications 2002/0066798, 2002/0066967, 2002/0068009, and 2002/0068010. The search for improved devices and systems, however, has continued.
  • This invention relates to devices and systems for dispensing volatile materials into the environment.
  • Several non-limiting embodiments are described herein, as are several components of the system, each of which may constitute an invention in its own right or together with other components.
  • FIG. 2 is an exploded perspective view of the major components of the device shown in FIG. 1 .
  • FIG. 2A is a schematic view of the heating element and spring arrangement of the device showing how the heating element can move in phantom.
  • FIG. 3 is a perspective view of one embodiment of a cartridge.
  • FIG. 4 is a top plan view of the cartridge shown in FIG. 3 .
  • FIG. 7 is a rear view of the cartridge shown in FIG. 3 .
  • FIG. 8 is an exploded perspective view showing the components of the cartridge shown in FIG. 3 .
  • FIG. 10 is a top view of the cartridge shown in FIG. 3 with a portion of a removable sealing material extending from the rear of the cartridge.
  • the system for dispensing volatile materials comprises one or more components containing one or more scents or aromatic materials.
  • the system preferably comprises a dispensing device, such as a device and one or more aromatic material-containing articles of manufacture, or “scent-containing articles of manufacture”, which may be provided in the form of fragrance “cartridges”.
  • a dispensing device such as a device and one or more aromatic material-containing articles of manufacture, or “scent-containing articles of manufacture”, which may be provided in the form of fragrance “cartridges”.
  • scent-containing articles of manufacture which may be provided in the form of fragrance “cartridges”.
  • Each cartridge can provide a single volatile composition, or a combination of different volatile materials, such as a combination of different scented materials. It should be understood, however, that the present invention is not limited to devices that are capable of emitting multiple scents, since various aspects of the invention are believed to be novel even when used on devices capable of emitting a single scent, or other type of volatile composition.
  • FIGS. 1 and 3 show one non-limiting embodiment of the system of the components for dispensing volatile materials into the environment.
  • the system shown in these figures comprises an apparatus (or “diffuser”, “dispensing device”, or simply “device”) 20 and a replaceable multiple compartment volatile composition-containing article of manufacture, such as cartridge 22 .
  • the drawings show one non-limiting example of the device and the volatile composition-containing article of manufacture.
  • the control buttons for the device are described in greater detail below.
  • the system of the present invention (that is, the device and cartridge) can be provided in many other suitable configurations.
  • FIG. 3 shows one non-limiting embodiment of the volatile composition-containing article of manufacture in the form of cartridge 22 as it appears when it is removed from the device 20 .
  • the cartridge 22 can contain a single volatile composition, such as a scented material, or multiple volatile compositions (e.g., multiple scented materials and/or other types of volatile compositions).
  • the cartridge 22 has a longitudinal centerline L, and a transverse centerline T.
  • the cartridge 22 comprises a housing portion (or shell) 24 , which has a top surface 26 , a bottom surface 28 , a front end 30 , a rear end 32 , and sides 34 .
  • the cartridge 22 can be of any suitable configuration.
  • the volatile compositions may be contained in or on an article that does not resemble the cartridge shown in the drawings.
  • the term “cartridge” as used herein, is not limited to articles that are in the form of cases or cassettes.
  • the volatile compositions could be provided in or on an article that resembles a disk, such as a compact disk (CD), rather than the article shown in the drawings.
  • CD compact disk
  • the volatile composition-containing article of manufacture such as cartridge 22 preferably also has one or more sealing mechanisms that seal the volatile compositions from evaporation.
  • the sealing mechanisms can be internal of the outer shell, or external of the outer shell of the article of manufacture.
  • the cartridge 22 can have a removable shipping seal for preventing the volatile compositions from evaporating before first use of the cartridge.
  • the cartridge 22 also comprises a sealing mechanism that seals the volatile compositions that are not intended to emit volatile compositions when the article is inserted into or placed on the device and volatile compositions are being emitted from the volatile compositions in one of the receptacles. It also is capable of sealing all the volatile composition receptacles when the article is removed from the device.
  • FIG. 8 shows the construction of this embodiment of the cartridge 22 in greater detail.
  • the cartridge 22 shown in FIG. 8 is but one possible embodiment of the article of manufacture.
  • Other types of volatile composition-containing articles can be provided which may not have some or all of the features of the cartridge 22 shown in FIG. 8 .
  • the cartridge 22 shown in FIG. 8 comprises several basic components. These include, from top to bottom: the upper part of the cartridge shell 36 ; a circular rotatable disk or tray 46 ; and the lower part of the cartridge shell 38 .
  • the rotatable tray 46 will be discussed first since, in this embodiment, the other components of the cartridge 22 are designed to cooperate with various features of the tray 46 .
  • This tray 46 is contained inside the shell of the cartridge 24 between the upper portion 36 and lower portion 38 thereof.
  • the tray 46 has a top surface 48 and a bottom surface 50 .
  • the top surface 48 of the tray 46 has the pockets 44 formed therein. Any suitable number of pockets 44 can be provided, and the pockets 44 can be in any suitable shape. In the embodiment shown in the drawings, there are five pockets 44 , and a blank space 51 between two of the pockets 44 for when the cartridge 22 is not intended to emit scents. In the embodiment shown in the drawings, the pockets 44 are in the shape of triangles with rounded corners.
